Subject: cpu: bmips: fix probe to get the address
X-Git-Tag: v2018.09-rc1~148^2~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=cef1f0c7a41226cdefec41b01868f2b4702d487c;p=platform%2Fkernel%2Fu-boot.git

cpu: bmips: fix probe to get the address

In the device tree, the address for cpu is located in
the node "cpus", not in the cpu node (for exemple cpu@0).
So when probing cpu, the cpu address must be read in the
cpu parent.

The commit "cpu: bmips: convert to use live dt"
(sha1: c444afbbefa103d567f197393d39ec0fcca21a0c)
change this behaviour and read the address in the
cpu node when probing cpu.

We fix this by reading the address in the cpu parent.
